Other ocular conditions include nystagmus, weakness of the orbicularis oculi muscle, abnormal pupil reactions and hypermetric / hypometric saccades. (26)
Videonystagmography showed no smooth pursuit, saccades had prolonged latencies to the right and were dysmetric with lateropulsion to the right (hypermetria to the right and hypometria to the left).
Saccades can be studied in terms of two of their elements: direction and amplitude.
A VNG battery of gaze, saccade, tracking, optokinetic, static, and dynamic positional tests were performed followed by the Dix-Hallpike test.
Corrective saccades were classified as a covert saccade when they occurred during the head movement and as an overt saccade when they occurred after the head movement.
Eye tracking can be described using a) fixation, b) fixation duration, c) total fixation duration, d) saccade, e) smooth pursuit, f) regress, and g) scanpath.
Fixations and saccades are the two major eye movements identified by eye trackers.
Analysis of the eye-movement recordings was no better than normal testing alone for detecting saccades. The experience of the examining physician had no impact on test performance characteristics.
Some of the measures that could be obtained with this equipment were the number of fixations, the total fixation time, the number of saccades, the total time in the trial, and qualitative analyses of ocular patterns, among several others.
However, the practical assessment for vHIT still confronts with lots of artifacts; 72% had abnormal disruptive saccades, 44% had at least one artifact, and 42% were uninterpretable.
And statistical parameters computed from recordings of saccades and fixations were compared.
To binocularly view an object of interest, two different types of eye movements are used: saccades and vergence.
